[Plugin: SEO Ultimate] Information is not saving

I’ve installed the plug in OK but everytime I try to submit meta data for each page – it doesn’t upload to the website.

The info is still there when I go back into the page but the site isn’t picking it up – please help!

I’;ve spent hours trying to fix it and no luck!
